SPINNING MACHINE FRAME Filed Dec. 1, 1958 '2 Sheets-Sheet 2 LOUIS BIRKIG'I INVE N TOR ATTORNEYS 2,993,331 SPHVNING MACHINE FRAME Louis Birkigt, Geneva, Switzerland, assignor to Brevets Aero-Mecaniques S.A., Geneva, Switzerland, a SWISS society Filed Dec. 1, 1958, Ser. No. 777,301 Claims priority, application Switzerland Dec. 3, 1957 2 Claims. (Cl. 57-1) This invention relates to spinning machines and the like, including all textile machines or frames provided with spindles and which are used either for the spinning operation proper or for twisting, stranding etc. It more particularly, but not exclusively concerns, amongst such machines, those with direct drive of the spindles, i.e. wherein the spindles are positively driven through appropriate gearings by at least one driving shaft extending along the length of the machine.

In accordance with this invention in a machine of the kind in question comprising base elements which directly support at least a row or rail of spindles, the framework of the machine comprises inverted U-shaped members which extend vertically above the said base elements, the said members serving as guides for the to and fro movements of at least one reciprocating element of the machine, more particularly of a rail of spinning rings, and also as supports for the upper elements of the said machine, such as a delivering device and/or a creel.

In the annexed drawings:

FIG. 1 is a diagrammatical fragmental side view of a spinning machine with direct drive of the spindles according to this invention.

FIG. 2 is an enlarged end view, some parts being removed and/or shown in section.

FIG. 3 is a transverse section taken along line III-III of 'FIG. 2.

In accordance with a preferred embodiment of this invention the spinning machine comprises at least one rail 1 supporting a row of vertical spindles 2, or preferably two such rails disposed on each side of the machine, the spindles of this row or of each row being driven by a common driving shaft. These spindles are adapted to cooperate with spinning rings carried by a supporting rail 3 which is vertically reciprocated with respect to the spindles, as for instance by means of a flexible connection 4 to which the aforesaid rail 3 is suspended.

In accordance with the invention the spindle rail or rails 1 is or are supported by base elements such as the stands 5, illustrated in FIG. 2, which are fixed onto the ground and which form part of the frame of the machine, and the said frame is completed by inverted U-shaped members which extend vertically above the aforesaid stands 5 while being appropriately spaced along the length of the machine, each one of these inverted U-shaped members comprising at least two columns 6 which form at the same time guides for the vertically reciprocatable ring rail 3 and supports for the upper elements of the spinning machine, as for instance for the drawing sets 7 and for a creel 8.

With such an arrangement there is no need for particular additional members for guiding the movements of the ring rail 3 since this role is played by the columns 6, i.e. by members of the framework of the machine, such members being in any manner required and moreover serving to support other elements of the machine.

Moreover the ring rail 3 is correctly guided since the guiding members which are provided for this purpose, i.e. the columns 6, are not liable to flex under the action htates Patent 0 Patented July 25, 1961 of bending stresses as this would be the case if the said elements were to be used as supports for the spindle rails 1 which would then be overhung laterally with respect to the said members.

Although in accordance with the above explanations the guiding of the ring rail 3 by the columns 6 could be carried into practice in a number of diiferent manners, it seems more convenient to use for this purpose the embodiment illustrated in FIGS. 2 and 3, and in which the columns 6 corresponding to each stand 5 are displaced longitudinally on each side of the mean transverse plane of the said stand in order to avoid that a column be equidistant with respect to two successive spindles, that is to say that a column be situated in a Zone which should preferably be left free, as for instance for permitting of swinging backwardly the hinged division plates provided between two successive spindles.

This invention finally provides a spinning machine the operation and the advantages of which (more particularly concerning the guiding of the ring rail) clearly result from the preceding description without requiring any further explanation.

It should besides be noted that a spinning machine constructed in accordance with the invention will be of reduced overall width without the specific pressure on the ground being increased.

The vertical guiding columns 6 may also be used as guides for other reciprocating members of the machine, as for instance for movable thread guides 9 or for movable circular anti-ballooning plates 10.

I claim:

1. A spinning machine which comprises, in combination, a stationary framework comprising a plurality of base elements resting on the ground and assembled to one another to form a longitudinal row and a plurality of inverted U-shaped members carried by said base elements and above them, each of said U-shaped members having its two vertical branches located on opposite sides, respectively, of the vertical middle plane of said row of elements, two spindle rails directly carried by said base elements on opposite sides of said middle plane, respectively, and extending parallelly to said plane, a plurality of spinning spindles carried by each of said spindle rails and forming a row along said rail, a plurality of spinning rings, each adapted to cooperate with one of said spinning spindles respectively, a ring rail unit for carrying said spinning rings, said ring rail unit including two elementary ring rails rigid with each other and located on opposite sides of said middle plane respectively, said ring rail unit being slidably guided by said vertical branches of said U-shaped members, and a plurality of upper machine parts carried by the top portions of said inverted U-shaped members and adapted to cooperate with said spindles and said rings respectively.

2. A machine according to claim 1 in which the two vertical brances of every inverted U-shaped member are located on opposite sides, respectively, of a vertical transverse plane perpendicular to said vertical middle plane, said transverse plane being at mid-distance between two consecutive spindles of each of said rows of spindles.
